Commercial Loan Calculator: A commercial property decision should begin with clear figures.

Use our Commercial Loan Calculator to estimate monthly repayments and the possible total cost of longer-term commercial borrowing.

The result can help you test different loan amounts, terms and interest rates before discussing your plans with an adviser.

At a Glance

Our Commercial Loan Calculator provides an illustrative estimate of commercial loan repayments.

Enter your proposed:

• Loan amount
• Interest rate
• Repayment term

The calculator can then estimate:

• Monthly repayments
• Total interest over the term
• Total amount repayable

The result is not a formal mortgage quotation or lending decision.

Commercial lenders will also assess the property, deposit, business, rental income, credit profile and proposed repayment structure.

Important information about your result

The figures produced by this calculator are estimates.

They do not represent:

• A formal mortgage offer
• An agreement in principle
• Confirmed lender affordability
• A property valuation
• A guaranteed interest rate
• Approval from a commercial lender

Actual repayments may include fees and costs not shown within a basic calculation.

Speak with a commercial mortgage adviser before making a financial commitment.

How to Use the Commercial Loan Calculator

The calculator uses three main pieces of information.

1. Enter the commercial loan amount

Enter the amount you are considering borrowing.

This may be the full loan required rather than the property’s purchase price.

For example, a property may cost £500,000. A borrower providing a £150,000 deposit may need a £350,000 commercial mortgage.

The lender will calculate the loan-to-value using the property valuation and requested loan.

2. Enter an estimated interest rate

Enter the annual interest rate you want to test.

Commercial mortgage rates are not determined by one standard pricing table.

The rate may depend on:

• The loan-to-value
• The property type
• The loan purpose
• The applicant’s credit profile
• Business or rental income
• Trading history
• Lease strength
• Loan size
• Repayment method
• Lender criteria

You can test several rates to understand how different pricing may affect repayments.

3. Select the proposed loan term

Choose the number of years over which the loan may be repaid.

A longer term can reduce the estimated monthly repayment.

However, extending the term may increase the total interest paid.

A shorter term may increase monthly payments but reduce the overall interest cost.

The suitable term must reflect the lender’s criteria and the borrower’s repayment capacity.

What Does the Calculator Result Mean?

The calculator should provide an early planning estimate.

It can help you understand the relationship between borrowing, interest and time.

Estimated monthly repayment

This is the approximate amount payable each month under the selected assumptions.

The figure may change when the lender confirms its rate, fees and repayment structure.

Total interest

This is the estimated interest charged across the chosen term.

It demonstrates why monthly affordability should not be considered alone.

A lower monthly repayment can still create a higher long-term cost.

Total amount repayable

This combines the original loan with the estimated interest.

Some lender fees, legal costs and valuation expenses may sit outside this figure.

Commercial Loan Repayment Example

Consider a business seeking a £300,000 commercial mortgage.

The business enters:

• Loan amount: £300,000
• Illustrative interest rate: 7%
• Repayment term: 20 years

The calculator estimates the monthly repayment and total interest using those assumptions.

The borrower can then compare the result with:

• A smaller loan
• A larger deposit
• A shorter term
• A longer term
• A different illustrative rate

This process does not identify the most suitable mortgage.

However, it can expose the financial effect of each decision.

Numbers do not make the decision. They show what the decision may require.

What Is a Commercial Loan?

A commercial loan is finance used for business or commercial purposes.

A commercial mortgage is normally secured against property used for business or investment.

It may help fund:

• Business premises
• Offices
• Retail units
• Warehouses
• Industrial property
• Commercial investment property
• Mixed-use buildings
• Care or medical premises
• Restaurants or hospitality property
• Refinancing of existing commercial property

Owner-Occupied and Commercial Investment Mortgages

Commercial mortgages are commonly divided into two broad categories.

Owner-occupied commercial mortgages

An owner-occupied mortgage may be used when a business buys premises from which it will trade.

Lenders may examine:

• Business accounts
• Management information
• Trading history
• Projected income
• Existing commitments
• Deposit size
• Business experience
• Property suitability

The business must usually demonstrate that repayments are sustainable.

Commercial investment mortgages

A commercial investment mortgage may fund property rented to another business.

The lender may review:

• Rental income
• Lease length
• Tenant covenant
• Rental coverage
• Vacancy risk
• Property condition
• Location
• Investor experience
• Deposit or available equity

The quality and stability of the lease can influence the lender’s assessment.

What Costs Are Not Always Included?

A basic commercial loan calculation may not include every transaction cost.

Possible additional costs include:

• Lender arrangement fees
• Property valuation fees
• Legal costs
• Broker fees
• Survey costs
• Accountancy costs
• Insurance
• Search fees
• Early repayment charges
• Exit or administration fees

Some fees may be added to the loan.

Adding fees can increase the balance and the interest charged.

Request a full cost illustration before proceeding.

How Does Loan-to-Value Affect a Commercial Mortgage?

Loan-to-value compares the proposed mortgage with the property’s value.

For example, a £300,000 loan against a £500,000 property represents 60% LTV.

A lower LTV can reduce the lender’s exposure.

However, it does not guarantee approval or a particular interest rate.

Lenders will still assess the property, borrower, income and loan purpose.

Valuation results may also affect the final LTV.

The lender will normally use its accepted valuation rather than the purchase price alone.

What Information May a Commercial Lender Request?

Document requirements vary between lenders and cases.

A lender may request:

• Business accounts
• Business bank statements
• Personal bank statements
• Tax calculations
• Tax year overviews
• Management accounts
• Asset and liability statements
• Lease documents
• Rental schedules
• Tenancy details
• Property information
• Proof of deposit
• Identification documents
• Evidence of experience
• Details of existing borrowing

Preparing the documents early can reduce avoidable delays.

Commercial Mortgage, Bridging Finance or Development Finance?

Not every commercial property project requires the same funding structure.

Commercial mortgage

A commercial mortgage may suit a longer-term property purchase or refinance.

Repayments are generally planned over several years.

Commercial bridging finance

Commercial bridging is short-term property finance.

It may be considered when timing, property condition or transaction structure prevents immediate long-term borrowing.

Interest may be retained, rolled up or serviced.

Read about commercial bridging finance when the funding need is temporary.

You can also test short-term costs using the Connect Lifetime Bridging Loan Calculator.

Development finance

Development finance may suit construction, conversion or substantial refurbishment projects.

Funds may be released in stages as work progresses.

Read our development finance guide when the project involves significant building work.

Can the Calculator Be Used for Buy-to-Let?

The calculator may illustrate standard repayment figures.

However, buy-to-let affordability is often assessed using rental income and lender stress testing.

Commercial investment property and residential buy-to-let are also assessed differently.

Read about buy-to-let mortgages when the security is a residential rental property.

Why Calculator Results and Lender Figures May Differ

A calculator applies the figures entered by the user.

A lender conducts a wider assessment.

The lender may change the calculation after reviewing:

• Its available products
• The confirmed property value
• The required loan amount
• The repayment method
• The business accounts
• The lease or rental position
• The applicant’s credit history
• Existing financial commitments
• Applicable fees
• The requested term

Commercial finance often requires individual underwriting.

Two similar properties may receive different outcomes because the borrowers, leases or purposes differ.

Questions to Consider Before Applying

Before approaching a lender, consider:

• What is the property being used for?
• How much deposit or equity is available?
• Can the business maintain the repayments?
• Is the income stable or seasonal?
• Does the property require refurbishment?
• Will the property be occupied or rented?
• Are the lease terms acceptable?
• Is long-term or short-term finance required?
• What costs sit outside the purchase price?
• Could repayments remain manageable if costs rise?

A calculation is most useful when the assumptions are realistic.

FAQs About the Commercial Loan Calculator

Is the Commercial Loan Calculator free to use?

Yes. You can use the calculator to test commercial loan repayment scenarios without submitting a mortgage application.

Does the calculator show the interest rate I will receive?

No. You must enter an illustrative interest rate.

Actual commercial mortgage rates depend on the lender, property and applicant.

Does using the calculator affect my credit score?

No. Using the calculator does not involve a credit search.

A lender or broker should explain before conducting any formal credit check.

Can I calculate interest-only commercial mortgage payments?

This depends on the calculator’s available settings.

Interest-only payments cover interest without reducing the original capital balance.

The full balance normally remains payable at the end of the term.

How much deposit is required for a commercial mortgage?

Deposit requirements vary.

They may depend on the property, business, loan purpose, income and lender criteria.

A larger deposit may reduce the loan-to-value, but it does not guarantee approval.

Are commercial mortgage rates higher than residential rates?

Commercial mortgages are assessed differently from residential mortgages.

Pricing depends on the lender’s view of the property, income, borrower and transaction risk.

Can a new business obtain a commercial mortgage?

It may be possible.

Lenders may examine experience, forecasts, deposit, business plans and alternative evidence when trading history is limited.

Is a commercial mortgage regulated by the FCA?

Many commercial mortgages are not regulated by the Financial Conduct Authority.

Regulation may depend on the borrower, property use and transaction structure.

Your adviser should explain the regulatory position before you proceed.
